A baby boy died this morning at a Bronx hospital, cops said.

The parents of 4-week-old Maximus Mussenden found him unresponsive after he slept in their bed, according to a police source.

The couple lives near the North Central Bronx Hospital in Woodlawn and brought him there shortly before 9:50 a.m., where he was pronounced dead.

There were no obvious signs of the trauma on the baby’s body, and the medical examiner will determine the cause of death.
